Hacking Switch Showing Error Screen After NAND Restore 9.0.1

[tantiveros]

I updated my switch using ChoiDujour to 9.0.1. Noticed some problems with goldleaf installing as well as the cartridge slot so I attempted to downgrade to 8.1.0 again using ChoiDujour however on reboot it only brought me to a an error screen after the nintendo logo. I then attempted to use my nand restore that I created before updating to 9.0.1 (nand restore is on 8.1.0) with no luck, same error screen. I tried using memloader and deleting my saves as well as using a Fat32 card instead of an exFat which I had originally been using with no luck, same error screen. Any advice on what I can do? I have a full nand backup at 8.1.0 with all my keys. Thank you all for your time.

1. Never downgrade via choidujourn while NOT formating the console.
2. Try maintanence mode and factory reset (vol up and down on boot).
3. Connect the switch to ethernet adapter and try the "secret" network update mode (idk how to get there now tho)
4. Rebuild your NAND.

Also, did you restore the boot 0/1 as well?

Yes I did back up the boot 0/1. I am able to get into maintenance mode, what should I attempt doing from there?

Factory reset the console.

Factory reset the console.

I got it running by factory resetting (which only provided the same error screen) and then updating via WiFi. Everything seems to be working. Such as home brew, auto rcm, and payloading. Anything I need to be aware of moving forward? Can I just now reuse The current version of gold leaf to reinstall my NSP’s?

I really appreciate all the help.

Yes. But probably update everything. Also, make a backup now and store it somewhere safe.
